Attempted the update by following instructions as noted.
Downloaded latest jar from download area, and pasted into:
_Lucee\lib\ext_ folder. Renamed the jar to “lucee.jar” and set original as “lucee.jar.bak”
Attempted Lucee\startup.bat and the cmd window opened and the startup ran, however was unsuccessful. A number of java exceptions were noted.
Please see following snippet for perhaps insight into how to fix (first error hit in the log):

Note, I rolled back to the original lucee.jar and was able to successfully return to v4.5.
Though regarding the 5.1 lucee.jar, it appears it has other dependencies that should be updated as well in the original jar set of v4.5?
